tsdecrypt reads an incoming MPEG transport stream over UDP/RTP and then decrypts it using keys obtained from OSCAM or a similar CAM server. Currently supported crypto systems are Conax, Cryptoworks, Irdeto, Viaccess, Mediaguard (Seca), Videoguard (NDS), Nagra, DRE-Crypt, and Bulcrypt. BISS and constant code words are also supported. tsdecrypt communicates with a CAM server using the cs378x (camd35 over TCP) protocol or the newcamd protocol.
mptsd receives MPEGTS streams from UDP/multicast or HTTP and combines them into one multiple program stream that is suitable for outputing to a DVB-C modulator. It has been tested with the Dektec DTE-3114 Quad QAM Modulator and it is used in production in couple of small DVB-C networks.
